 # docker-terasology
 
-check out and build with
-```docker build .```
+Automatic builds are provided by dockerhub and my own jenkins instance.
+For all enthusiasts who just want to have a running server:
+- `docker pull qwick/terasology:latest`
+- or with version: `docker pull qwick/terasology:1.2.1-alpha`
 
-or use the image on dockerhub:
-https://registry.hub.docker.com/u/qwick/terasology/
+For all developers who want a unstable build for debugging or just testing purposes:
+- `docker pull qwick/terasology:unstable-latest`
+- a versioned tag is available too.
 
-## Latest changes
-### 2016-03-16: [Alpha release 1; Engine v1.0.0](https://github.com/MovingBlocks/Terasology/releases/tag/v1.0.0)
-I'm again a little late with the docker image update, sorry! ;-)
+Versioned tags may change over time.
+
+## Versioning
+
+To avoid confusion here the docker image tag schema:
+
+Stable:
+- `<engineVersion>-<displayVersion>` e.g. `1.2.1-alpha`
+
+Unstable:
+- `unstable-<engineVersion>-<buildNumber>` e.g. `unstable-1.2.2-SNAPSHOT-1806`
